How to include OAuth lib in the pfSense 2.1.4 iso image.

Dear All,

I'm very interested to include OAuth2 in pfSense 2.1.4.
One question: How I can include the OAuth library in pfSense 2.1.4.iso?
I studied your customization and I saw that its need to include:
- Oauth lib in etc/inc path
- Edit index.php in captiveportal folder
- Edit service-captiveportal.php for showing the oauth authentication method as well.

I tried to do include the lib in the iso but while I throw in virtualbox I receive kernel module not found.
Any suggestion?
Cheers
SM
